application led October 24, 1918. Serial No. 259,524.

Be it known that I. Fimo F. Hamas, a citizen of the. United States. residing at Los Angeles. in therountuvv of Los Angeles and State of California. have invented new and useful In'iprovements in Gas-Generators. ot' which the following is a specification.

M v invention relates to a buine and more partieularl;v to a gas generating burner.

An object of invinvention is to. provide asiniple and serviceable burner tor use' in a cooking stove orramge.

Another object is to provide a burner for use in a stove or range in connection with which kerosene or coal as fuel.

With these, andotherobjeets in view in v invention consists in the construction. eombination and arrangement ot' partV hereinafter described and claimed. l

In lthe accompanying drawings whieh torni a part of this specification.

-Fi'g'uie l a fragmentary view in perspeetiveof a Cooking stove provided with abut-ner embodying. the principles ot my invention and showing its eonneetions with a kerosene supply tank.

Fig.' 2 an `enlarged view in perspective ot' `the burner shown in Fig'. l. f

eil may be employed Fig. 3 is an enlarged transverse section of the burner shown in Fig. 2, taken on the i line 3.-3 of Fig. 2.

As shown inv Fig. the. burner is mounted in a'fire box 1t) of'a stove 11, a supply pipe 12 being led into the tirebox through holes in the side o't'tlie stove and the end plate -13 of the tire boxlii'iiiig.

l The supplyI pipe is equipped with a regulating valve 1-'l and is attached through a'needle. valve 15y to au oil tank 16. The oil tank is providedl with a )ressure frage 17 and `is connected to an yair pump 18 by a tube i9 through a out. ott' valve 2t. The burner proper comprises 4a vertical end plate 2l, having a straight lower edffe or base' 22 ada, ted to rest on h the stovel grate so that it extends erosswise of the lire box on one end of the grate. The

late is trianffular in eneral forni and has annular flanges 23 and 24 formed' on itsy inner face at its ends elose to its base and a boss 25 formed on its u ward extension 21 midway between its ein` s. Parallel side -tubesI 255 and 27 extend lengthwise of the burner and have one end lixed in the annular tiano'es 22 and 23. these ends being held in the flanges and against the end plate by set screws in the flanges. The opposite ends of these parallel tubes are connected by an vertical tube ris joined to the vcross tube 29 at its middle. It extends upwardly and terminates` in an enlarged right angled elbow 33 having its opening turned toward the end plate 21. A mixing tubell made 1n the form of a right angle lelbowy has its shorter horizontal extension teleseoped into the. elbow 33 and held therein by a set screw 35 while its longer vertical extension 3G opens downwardly below the burner.l A boss 37 is formed onthe louter angle of the elbow so as to face the end plate in horizontal aliiienient with the boss formed on the upper projection of the end plate. A generating tube 38 extends through the boss 25 in the upper extensionl of the end plateI and is connected to the supply tube l2 b v a union 39. The other end ot the generating tube extends through the boss 37 formed on the mixing tube 34 and terminatesI in a mixing chamber 4() within the' mixing tube.

This end of the generating tube wliieh is' heldin position by a set screw 41 1n theL boss 37.is equipped with a'eap 42 having a small orifice 43 at its, center. `This eap and orifice, constitiite the nozzle 0f the gen# erating tube. Extending erosswise ot' the burner between tl'ie'parallelfside 4tubes 2G and 27 yis a vseries of parallel tubes 44@ hav-' ing their ends fixedl in the walls of the sider tubes and opening Within the tubes.y These cross tubes are provided with saw out open-` the gas vents of the burner. f Ageneralting ings 45 in their upturned sides wliieh trough 4G extends lengthwise of the. billrnor directly under the generatingtube 395 and parallel t0 it between the. end platey 2l, and the mixing tube 34 resting on the cross .tubes 44. supportingbar 47 extends lengtltiwisey of the burner under. the lburner tube" di reetlyunderthe generating'trough, one of! its ends .terminating in a hole. 48 in thd end plate and the other in va-boss 49 formed on the mixing tube. Bolts 50 extending vertically through the supporting bar /lfand the bottom of the geiierating trough 46 s'lgrve to hold the generating trough in plaee.; A shorter supporting bar 5l extends in allinement with supporting bar 47 between the ino crosspipe and' themixing pipe 34C, its ends terminating in bosses 52 and 53 formed on these tubes in horizontal alinenient with each other. The interior of the generating tube is provided with a plurality of straight wires' extending vlengthwise of the tube,

`their purpose being to retard the flow of oil through thegenerator,` tube and at thesame time to provide a relatively large heat retaining substance as well as a large surface in contact with theoil. A Operation: The connections having been made as indicated in Fig. 1.7 a hand pump 18 is operated to obtain-required pressure inA the oil tank and valve 20 is closed to retain Mineral wool or some othe'i non,4

the air. combustible material is placed in the generating trough 4G and alcohol is poured upon The alcohol is then lighted and ,permitted to burn until the heat from the burn-. ing `alcohol rises against the generating tube and heats it to the-'required temperature,

whereupon the valves 14 and 15 are opened to admit the oil. AOil iiows through the generating'tube and'conies into contact with the heated metal, whereupon it is vaporized. The vapor 0r gas emerging into the mixing chamber through the orifice 43 with consid erable force, draws air upwardly through the open end of the mixing tube and the mixture of air and gas passes through the conneeting tube 32, the end tube 29 and the side tubes Q6 and 27, thence into the ends ot' the cross'tubes ist and out through the slots where it is burned.' v The series of cross tubes here provided produces a large andk well distributed burn-ing surface especially well adapted for a cooking stove. The generator tube is so placed that, once the burner has been started, the hea-tfot the burner actingl 1.
